I don't get the concern either. Instead for 2 block walls just put four. It is not like they are intelligent. You know they are just going to run at you so it seems like the defense is just thicker walls. My guess is that these types of players don't actually want a safe base. They want a zombie slaughterhouse where zombie pathing is exploited to funnel them into a Cuisinart for easy loot gathering. All the more reason for something like a demolisher.I don’t see what everyone is worried about with the demolisher. We have no idea how much damage it can do, how often they will spawn, how fast they move, etc. We don’t know what the best tactic will be defending a base against them. If it’s OP, they will change it or add in ways to deal with it... but we kinda have to see it in action first, not to mention, in an environment we haven’t played in yet.
I can promise I invest as much time building a base with other players than the single player guys do. Recovering from your base being breached by zombies is not a big deal.
